Title: Crimped connector assembly for fiber optic cables or the like
IPC: G02B6/36
Filed: 1979-09-04
Abstract: In a fiber optic cable, the crimping must be done to the strength members which surround the optical fibres. A connector body is provided for receiving the optical fibers of the cable and has a rear end portion 26 over which the strength member of the cable is positionable. The rear end portion of the connector body is provided with one or more annular crimp receiving grooves. A ferrule member 14 is positionable over the grooved rear end portion of the connector body for crimping the strength member 20 between the ferrule member and the connector body. The ferrule member is crimped to have one or more crimping ribs 34 which are nested in the grooves of the connector body clamping the strength member therebetween. The included grooves of the connector body are smaller than the ribs of the ferrule member so as to increase the number of crimping areas between the connector body and the ferrule member. <IMAGE>

Title: Pressure die casting method and apparatus for production of rotor having radial vanes
IPC: B22D17/22
Filed: 1981-01-09
Abstract: A split die for pressure die casting a vaned rotor which comprises a vane portion where radial vanes are formed on a central shaft and a base portion where the central shaft has no vanes thereon, is divided radially into a plurality of die segments that can be moved radially inwardly to define a die cavity and outwardly to open the die.

Immediately after solidification of molten metal in the die cavity in a region to become the vane portion of the rotor, initially only the first part (54a) of each die segment is moved radially outwardly (Figure 5A) to prevent this part of the die from significant wear. The second part (54b) of each die segment is moved radially outwardly (Figure 5B) after solidification of the molten metal in the remaining region to become the base portion of the rotor. <IMAGE>

Title: Acousto-optic isolator
Inventor: HEEKS JOHN STUART
IPC: H04B10/43
Filed: 1981-11-03
Abstract: An acousto-optic isolator for a semiconductor laser diode D comprises a Fabry-Perot resonator R tuned to the laser optical frequency f0 followed by an acousto-optic Bragg diffraction device utilising surface acoustic waves of frequency fa launched from the transducer T. Light focussed by lens L to the load via output 0 has a resultant frequency f0 + fa. Any light reflected from the load suffers a further change in frequency to f0 + 2fa in the diffraction device and hence is blocked by the resonator. Undiffracted light can be detected to photo-detector P and used in a feedback control loop F to stabilise the light source D to the resonator. <IMAGE>

Title: Method of and apparatus for measuring and correcting registration on a printed sheet
Inventor: PANNIER LUTZ
IPC: B65H23/188
Filed: 1982-06-03
Abstract: The method comprises measurement of the position of the register marks relative to each other, evaluating the measurement to determine deviations from a predetermined desired value, and forming an actuating signal to regulate registration. For the measuring step, in each printing operation there is measured either the distance between two register marks 15, 16 printed by a forward printing mechanism (2, 3) on each occasion and between one register mark 4 printed by the forward printing mechanism and one register mark 7 printed by the succeeding printing mechanism (5, 6) or the distances between the register mark flanks. Thereafter a comparison with a desired value for this distance is carried out, which has as its result the magnitude of any mackle. By a comparison with the measured result from the preceding printing cycle, the direction of the mackle is established and with the established mackle values a correction of the measured result of the present printing cycle is carried out. The corrected measured result is utilized as an actual value for the register regulation. The distances are measured by counting pulses generated at 12 and gated by photo- electric detection of the marks at 8. <IMAGE>

Title: A double grid for fluorescent lamp units
Inventor: WILLUMSEN SVEN-AAGE
IPC: F21V11/06
Filed: 1981-12-02
Abstract: The grid comprises a plurality of light passages (3) surrounded by walls (4, 5, 6, 7) of an appropriate height and located at a mutual, appropriate distance permitting light from a light source (9) to flow through said light passages. The grid comprises at least two independent plane parallel grid members (1, 2) located closely to each other or at a predetermined mutual distance. By means of retaining means (8), e.g. short, snap-lock-like connections, the grid members may be secured to each other. The grid members may be of the same or different type in such a manner that both for instance may be shielding grids, or one grid member may be a shielding grid whereas the other, preferably the lower grid member may be a mirrored low luminance grid. By manufacturing the grid of two mutually spaced grid members, it is possible to place the walls (4, 5, 6, 7) at a greater mutual distance than previously, which ensures a material saving while maintaining the shielding angle usually aimed at. Such a construction furthermore ensures that the thickness of the walls may be reduced compared to known grids, which involves an additional material saving. The total weight of the grid is thereby essentially reduced. Furthermore, new light effects are permitted by providing the grid members with different colours.

The luminance signal in each line is likewise split into two parts LLA and LRA (or LLB and LRB) for images L and R respectively. These two images are then used to produce a three-dimensional image. <IMAGE>
